My Server is 64-bit & has 32 GB of RAM on both the nodes.One Instance is running on both the nodes .We didnot limited the RAM and we have seen lot of paging on this server .We decided to limit the Memory to 14GB inorder to leave 4GB to the OS .

DO i need to restart the Server after we changed the Memory ?

You do not need to restart SQL Server. If you only have one instance on this cluster, then I wouldn't limit the memory so much. You only need 1.5-2GB for the OS. I would recommend giving the instance 28-30GB.

Also, did you "lock pages in memory" for the SQL Server account?

Yes,SQL Server account was added to that .On this Cluster box ,i have 2 servers running on each node .Why i am thinking to limit to 14 becoz ,If the other server fails to the same node .It will take 28GB and give 4GB to OS .

I am planning to use this script to update the memory .

Exec sp_configure 'show advanced options',1;
RECONFIGURE;
GO
Exec sp_configure 'min server memory',1024;
RECONFIGURE;
GO
Exec sp_configure 'max server memory',14336;
RECONFIGURE;
GO
Exec sp_configure 'show advanced options',0;
RECONFIGURE;
GO

Oh ok, I thought you only had one instance. If you have two instances, then yes I would agree with that.
